OMIA:001485-9615 : Dwarfism, PRKG2-related in Canis lupus familiaris (dog) |
In other species: taurine cattle
Categories: Skeleton phene (incl. short stature & teeth)
Possibly relevant human trait(s) and/or gene(s) (MIM number): 601591 (gene)
Links to MONDO diseases: No links.
Mendelian trait/disorder: yes
Mode of inheritance: Autosomal recessive
Considered a defect: yes
Key variant known: yes
Year key variant first reported: 2021
Cross-species summary: 'Dwarfism, Angus' was renamed to 'Dwarfism, PRKG2-related' [29/10/2021]
Inheritance: Rudd Garces et al. (2021) reported evidence consistent with autosomal recessive inheritance.
Mapping: Rudd Garces et al. (2021): "... combined linkage and homozygosity mapping assigned the most likely position of a potential genetic defect to 34 genome segments, totaling 125 Mb."
Molecular basis: Rudd Garces et al. (2021): "The genome of an affected dog was sequenced and compared to 795 control genomes. The prioritization of private variants revealed a clear top candidate variant for the observed dwarfism. This variant, PRKG2:XM_022413533.1:c.1634+1G>T, affects the splice donor site and is therefore predicted to disrupt the function of the PKRG2 gene .... "
Genetic engineering:
Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing
Clinical features: Rudd Garces et al. (2021) "investigated a family of nine Dogo Argentino dogs, in which two dogs were affected by disproportionate dwarfism. Radiographs of an affected dog revealed a decreased level of endochondral ossification in its growth plates, and a premature closure of the distal ulnar physes."
Breed:
Dogo Argentino (Dog) (VBO_0200445).

Variants
By default, variants are sorted chronologically by year of publication, to provide a historical perspective.
Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending
order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column
headers.
WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
